Just got back from there. Roads are very good, stick to the speed limits as they have cameras. If you are renting a car at the rental counter they will likely try and upsell you insurance. I do not know what you will do to cover any excess/damage on the vehicle. I have no connection with either of these, but to rent the car I went through rentalcars.com and rented from Goldcar. At the Goldcar counter they will try to sell you their insurance and my assumption is that all car rental companies will do the same. So, I took out an annual policy with a company that covers any excess and damage which was less than the price that rentalcars.com wanted to offer me for their "full protection". So what I am saying is that you might want to have a look around.
The other thing is to make sure you know whether your car is diesel or petrol before you fill up !
